Abstract
A rotary transfer press comprising a crown, a bed, a post extending from the bed to the crown, a slide upwardly and downwardly movable as guided along the post, a drive assembly for moving the slide upward and downward, a plurality of working stations disposed in a circular arrangement and each provided with a press die, and a transport assembly for transferring workpieces from each of the stations to the next station in succession. The press can be installed in a small space, and the workpieces are feedable to and dischargeable from the press at any of the stations. The press dies are also replaceable at any station.
Claims7
A rotary transfer press comprising a bed;
- a post mounted upright on the bed, a slide upwardly and downwardly movable as guided along the post;
- a vertically driving assembly for moving the slide upward and downward;
- a plurality of working stations disposed in a circular arrangement and each provided with a pair of press dies;
- an annular feed bar extending in the vicinity of the working stations, said feed bar being provided with a toothed portion therealong;
- and a feed bar driving mechanism comprising a feeding drive shaft mechanically connected to and rotated by the vertically driving assembly, cam means actuated by the rotation of the drive shaft, a lever actuated and rocked by the cam means, a rack bar connected to and moved reciprocally linearly by the lever, a gear mounted on a shaft and meshing with the rack bar, and a pinion mounted on the same shaft as said gear and meshing with the toothed portion of the feed bar, whereby the rotation of the feeding drive shaft is transmitted to the feed bar as an intermittent reciprocal turning motion.
